Generally, that airspace from the surface to 2,500 feet above the airport elevation (charted in MSL) surrounding those airports that have an operational control tower. The configuration of each Class D airspace area is individually tailored, and when instrument procedures are published, the airspace will normally be designed to contain the procedures.

Generally, that airspace from the surface to 4,000 feet above the airport elevation (charted in MSL) surrounding those airports that have an operational control tower, are serviced by radar approach control, and that have a certain number of IFR operations or passenger emplanements. Although the configuration of each Class C airspace area is individually tailored, the airspace usually consists of a 5 NM radius core surface area that extends from the surface up to 4,000 feet above the airport elevation, and a 10 NM radius shelf area that extends from 1,200 feet to 4,000 feet above the airport elevation.

Grasp the coil of an electromagnet in such a way that the fingers encircle the coil in the same direction electrons are flowing (from the negative terminal of the power supply to the positive terminal). The thumb points to the north pole of the electromagnet formed by the coil.
Industry:Aviation
Gravity-operated air valves mounted on the bottom of the gyro housing in a gyro horizon instrument. Air used to spin the gyro leaves the housing through these valves. If the gyro should tilt, the size of the holes covered by the valves changes, and the exhausting air produces a force that causes the gyro to erect.

Hand-operated shears used for cutting sheet metal. The most generally used snips are called tin snips, because they are commonly used to cut commercial sheet metal which is often (though incorrectly) called “tin.”
